SUMMARY OF INVENTION Technical Problem

As described above, Non-patent Document 1 describes the results of studies on the characteristics as a host, material of the compound having two carbazolylphenyl groups bonded to the carborane structure. However, as a result of actual evaluation by the present inventors of the characteristics as a host material of the compound having two carbazolylphenyl groups bonded to the carborane structure, it has been found that the characteristics are not sufficiently satisfactory, and there is a demand of providing a host material having better characteristics.

The inventors then start to investigate variously a group of compounds having a carborane structure, have firstly found that among many compounds having a carborane structure, a group of compounds having a structure containing a carborane structure having an acceptor and a donor bonded thereto has usefulness as a host material and the like, and have decided to continue further investigations. As described above, Patent Document 1 describes an example using the compound containing a carborane structure having silyl groups bonded thereto as a host material of a light-emit ting layer. However, a silyl group does not function as an acceptor or a donor, and Patent Document 1 does not describe a compound containing a carborane structure having an acceptor and a donor bonded thereto. Patent Document 2 describes the usefulness of a compound containing a carborane structure having two carbazolylphenyl groups bonded thereto as a material for an electron transporting layer, and furthermore Non-patent Document 1 describes the result of investigations on the characteristics of the compound as a host material. Herein, a carbazolylphenyl group functions as a donor. However, Patent Document 1 and Non-patent Document 1 do not describe a compound containing a carborane structure having both a donor and an acceptor bonded thereto. Accordingly, for a compound containing a carborane structure having an acceptor and a donor bonded thereto, the usefulness as a host material, and the like of the compound cannot be estimated.

Under the circumstances, the inventors have further made investigations on the usefulness as a host material and the like of a compound containing a carborane structure having an acceptor and a donor bonded thereto, and have made accumulated studies for finding a compound having excellent characteristics as a host material and the like. Furthermore, the inventors have made earnest investigations for providing a general formula of compounds useful as a host material and generalizing the structure of an organic light-emitting material having a high light emission efficiency.

In an organic electroluminescent device, carriers are injected from an anode and a cathode to a light-emitting material to form an excited state for the light-emitting material, with which light is emitted. In the case of a carrier injection type organic electroluminescent device, in general, excitons that are excited to the excited singlet, state are 25% of the total excitons generated, and the remaining 75% thereof are excited to the excited triplet state. Accordingly, the use of phosphorescence, which is light omission from the excited triplet state, provides a high energy utilization. However, the excited triplet state has a long lifetime and thus causes saturation of the excited state and deactivation of energy through mutual action with the excitons in the excited triplet state, and therefore the quantum yield of phosphorescence may generally be often not high. A delayed fluorescent material emits fluorescent light through the mechanism that the energy of excitons transits to the excited triplet state through intersystem crossing or the like, and then transits to the excited singlet state through reverse intersystem crossing due to triplet-triplet annihilation or absorption of thermal energy, thereby emitting fluorescent light. It is considered that among the materials, a thermal activation type delayed fluorescent material emitting light through absorption of thermal energy is particularly useful for an organic electroluminescent device. In the case where a delayed fluorescent material is used in an organic electroluminescent device, the excitons in the excited singlet state normally emit fluorescent light. On the other hand, the excitons in the excited triplet state emir, fluorescent light through intersystem crossing to the excited singlet state by absorbing the heat generated by the device. At this time, the light emitted through reverse intersystem crossing from the excited triplet state to the excited singlet state has the same wavelength as fluorescent, light since it is light emission from the excited singlet state, but has a longer lifetime (light emission lifetime) than the normal fluorescent light and phosphorescent light, and thus the light is observed as fluorescent light that is delayed from the normal fluorescent light and phosphorescent light. The light may be defined as delayed fluorescent light. The use of the thermal activation type exciton transition mechanism may raise the proportion of the compound in the excited singlet state, which is generally formed in a proportion only of 25%, to 25% or more through the absorption of the thermal energy after the carrier injection. A compound that emits strong fluorescent light and delayed fluorescent light at a low temperature of lower than 100° C. undergoes the intersystem crossing from the excited triplet state to the excited singlet state sufficiently with the heat of the device, thereby emitting delayed fluorescent light, and thus the use of the compound may drastically enhance the light emission efficiency,

The use of the compound represented by the general formula (1) of the invention as a host material or a light-emitting material of a light-emitting layer may provide an excellent organic light-emitting device, such as an organic photoluminescent device (organic EL device) and an organic electroluminescent device (organic EL device). At this time, the compound represented by the general formula (1) of the invention may have a function of assisting light emission of another light-emitting material contained in the light-emitting layer, i.e., as a so-called assist dopant. Specifically, the compound represented by the general formula (1) of the invention contained in the light-emitting layer may have a lowest excited singlet energy level that is between the lowest excited singlet energy level of the host material contained in the light-emitting layer and the lowest excited singlet energy level of the another light-emitting material contained in the light-emitting layer.

The organic photoluminescent device has a structure containing a substrate having formed thereon at least a light-emitting layer. The organic electroluminescent device has a structure containing at least an anode, a cathode and an organic layer formed between the anode and the cathode. The organic layer contains at least a light-emitting layer, and may be formed only of a light-emitting layer, or may have one or more organic layer in addition to the light-emitting layer. Examples of the organic layer include a hole transporting layer, a hole injection layer, an electron barrier layer, a hole barrier layer, an electron injection layer, an electron transporting layer and an exciton barrier layer. The hole transporting layer may be a hole injection and transporting layer having a hole injection function, and the electron transporting layer may be an electron injection and transporting layer having an electron injection function. A specific structural example of an organic electroluminescent device is shown in FIG. 1. In FIG. 1, the numeral 1 denotes a substrate, 2 denotes an anode, 3 denotes a hole injection layer, 4 denotes a hole transporting layer, 5 denotes a light-emitting layer, 6 denotes an electron transporting layer, and 7 denotes a cathode.

The members and the layers of the organic electroluminescent device will be described below. The descriptions for the substrate and the light-emitting layer may also be applied to the substrate and the light-emitting layer of the organic photoluminescent device.

Substrate

The organic electroluminescent device of the invention is preferably supported by a substrate. The substrate is not particularly limited and may be those that have been commonly used in an organic electroluminescent device, and examples thereof used include those formed of glass, transparent plastics, quartz, and silicon.

Anode

The anode of the organic electroluminescent device used is preferably formed of as an electrode material a metal, an alloy or an electroconductive compound each having a large work function (4 eV or more), or a mixture thereof. Specific examples of the electrode material include a metal, such as CuI and an electroconductive transparent material, such as CuI, indium tin oxide (ITO), SnO₂ and ZnO. A material that is amorphous and is capable of forming a transparent electroconductive film, such as IDIXO (In₂O₃—ZnO), may also be used. The anode may be formed in such a manner that the electrode material is formed into a thin film by such a method as vapor deposition or sputtering, and the film is patterned into a desired pattern by a photolithography method, or in the case where the pattern may not require high accuracy (for example, approximately 100 μm or more), the pattern may be formed with a mask having a desired shape on vapor deposition or sputtering of the electrode material. In alternative, in the case where a material capable of being applied as a coating, such as an organic electroconductive compound, is used, a wet film forming method, such as a printing method and a coating method, may be used. In the case where emitted light is to be taken out through the anode, the anode preferably has a transmittance of more than 10%, and the anode preferably has a sheet resistance of several hundred Ohm per square or less. The thickness thereof may be generally selected from a range of from 10 to 1,000 nm, and preferably from 10 to 200 nm, while depending on the material used.

Cathode

The cathode is preferably formed of as an electrode material a metal having a small work function (4 eV or less) (referred to as an electron injection metal, an alloy or an electroconductive compound each having a small work function (4 eV or less), or a mixture thereof. Specific examples of the electrode material include sodium, a sodium-potassium alloy, magnesium, lithium, a magnesium-cupper mixture, a magnesium-silver mixture, a magnesium-aluminum mixture, a magnesium-indium mixture, an aluminum-aluminum oxide (Al₂O₃) mixture, indium, a lithium-aluminum mixture, and a rare earth metal. Among these, a mixture of an electron injection metal and a second metal that is a stable metal having a larger work function than the electron injection metal, for example, a magnesium-silver mixture, a magnesium-aluminum mixture, a magnesium-indium mixture, an aluminum-aluminum oxide (Al₂O₃) mixture, a lithium-aluminum mixture, and aluminum, are preferred from the standpoint of the electron injection property and the durability against oxidation and the like. The cathode may be produced by forming the electrode material into a thin film by such a method as vapor deposition or sputtering. The cathode preferably has a sheet resistance of several hundred Ohm per square or less, and the thickness thereof may be generally selected from a range of from 10 nm to 5 μm, and preferably from 50 to 200 nm. For transmitting the emitted light, any one of the anode and the cathode of the organic electroluminescent device is preferably transparent or translucent, thereby enhancing the light emission luminance.

The cathode may be formed with the electroconductive transparent materials described for the anode, thereby forming a transparent or translucent cathode, and by applying the cathode, a device having an anode and a cathode, both of which have transmittance, may be produced.

Light-Emitting Layer

The light-emitting layer is a layer, in which holes and electrons injected from the anode and the cathode, respectively, are recombined to form excitons, and then the layer emits light. A light-emitting material may be solely used as the light-emitting layer, but the light-emitting layer preferably contains a light-emitting material and a host material.

In the case where the compound represented by the general formula (1) as a host material, one kind or two or more kinds selected from a group of compounds represented by the general formula (1) may be used. The light-emitting material may be a fluorescent light-emitting material or may be a phosphorescent light-emitting material, and in the case using a fluorescent light-emitting material, the light-emitting material is preferably one that emits delayed fluorescent light. A high light emission efficiency can be obtained thereby. In order that the organic electroluminescent device and the organic photoluminescent device of the invention exhibit a high light emission efficiency, it is important that the singlet excitons and the triplet excitons generated in the light-emitting material are confined in the light-emitting material. Accordingly, the light-emitting material combined with the compound represented by the general formula (1) is preferably a compound that has excited singlet, energy and excited triplet energy, at least one of which is higher than those of the compound represented by the general formula (1). As a result, the singlet excitons and the triplet excitons generated in the light-emitting material of the invention are capable of being confined in the molecules of the light-emitting material, thereby eliciting the light emission efficiency thereof sufficiently.

Examples of the light-emitting material combined with a host material containing the compound represented by the general formula (1) include a light-emitting material capable of emitting delayed fluorescent light. Preferred examples of the light-emitting material will be described below, but the light-emitting material capable of being used in the invention is not limited to the following examples.

The host material used may be are organic compound that has excited singlet energy and excited triplet energy, at least one of which is higher than those of the light-emitting material of the invention. Even though the singlet excitons and the triplet excitons are not confined sufficiently, however, a high light emission efficiency may be obtained in same cases, and thus a host material that is capable of achieving a high light emission efficiency may be used in the invention without any particular limitation.

In the organic light-emitting device and the organic electroluminescent device of the invention, the light emission occurs in the light-emitting material of the invention contained in the light-emitting layer. The emitted light contains both fluorescent light and delayed fluorescent light. However, a part of the emitted light may contain emitted light from the host material, or the emitted light may partially contain emitted light from the host material.

Similarly, the hole barrier layer may be disposed between the light-emitting layer and the electron transporting layer, and inhibits holes from passing through the light-emitting layer reward the electron transporting layer. The barrier layer may also be used for inhibiting excitons from being diffused outside the light-emitting layer.

Electron Transporting Layer

The electron transporting layer is formed of a material having a function of transporting electrons, and the electron transporting layer may be provided as a single layer or plural layers.

The electron transporting material (which may also function as a hole barrier material in some cases) needs only to have a function of transporting electrons, which are injected from the cathode, to the light-emitting layer. Examples of the electron transporting layer that may be used herein include a nitro-substituted fluorene derivative, a diphenylquinone derivative, a thiopyran dioxide derivative, carbodiimide, a fluorenylidene methane derivative, anthraquinodimethane and anthrone derivatives, and an oxadiazole derivative.

The organic electroluminescent device thus produced by the aforementioned method emits light on application of an electric field between the anode and the cathode of the device. In this case, when the light emission, is caused by the excited singlet energy, light having a wavelength that corresponds to the energy level thereof may be confirmed as fluorescent light and delayed fluorescent light. When the light emission is caused by the excited triplet energy, light having a wavelength that corresponds to the energy level thereof may be confirmed as phosphorescent light. The normal fluorescent light has a shorter light emission lifetime than the delayed fluorescent light, and thus the light emission lifetime may be distinguished between the fluorescent light and the delayed fluorescent light.

The phosphorescent light may substantially not observed with a normal organic compound, such as the compound of the invention, at room temperature since the excited triplet energy is converted to heat or the like due to the instability thereof, and is immediately deactivated with a short lifetime. The excited triplet energy of the normal organic compound may be measured by observing light emission under an extremely low temperature condition.

The organic electroluminescent device of the invention may be applied to any of a single device, a structure with plural devices disposed in an array, and a structure having anodes and cathodes disposed in an X-Y matrix. According to the invention, an organic light-emitting device that is largely improved in light emission efficiency may be obtained by adding the compound represented by the general formula (1) in the light-emitting layer. The organic light-emitting device, such as the organic electroluminescent device, of the invention may be applied to a further wide range of purposes.

Tokito, C. Adachi and H. Murata, “Yuki EL Display” (Organic EL Display) (Ohmsha, Ltd.). In particular, the organic electroluminescent device of the invention may be applied to organic electroluminescent illumination and backlight which are highly demanded.

Example 3 Production and Evaluation of Organic Photoluminescent Device Using Compound 1 as Light-Emitting Material

Toluene solutions of the compound X having a concentrations of 10⁻³ M, 10⁻⁴ M, and 10⁻⁵ M were prepared in a glove box under an Ar atmosphere.

The compound 1 was vapor-deposited on a quartz substrate by a vacuum vapor deposition method under condition of a vacuum degree of from 2 to 7.0×10⁻⁴ Pa to form a thin film of the compound 1 to a thickness of 100 nm, thereby providing an organic photoluminescent device.

The specimens using the compound 1 were measured for light emission and absorption spectra with excitation light of 230 nm. FIG. 6 shows the light emission and absorption spectra of the toluene solutions before bubbling with nitrogen and the organic photoluminescent device measured in the air, and FIG. 7 shows the light emission and absorption spectra of the toluene solutions after bubbling with nitrogen and the thin film organic photoluminescent device measured in a nitrogen-containing atmosphere.

The photoluminescence quantum efficiency of the toluene solution of the compound 1 before bubbling with nitrogen was 1.9% for the toluene solution of 10⁻³ M, 2.1% for the toluene solution of 10⁻⁴ M, and 2.7% for the toluene solution of 10⁻⁵ M, and that after bubbling with nitrogen was 76.3% for the toluene solution of 10⁻³ M, 17.8% for the toluene solution of 10⁻⁴ M, and 5.3% for the toluene solution of 10⁻⁵ M. The photoluminescence quantum efficiency of the organic photoluminescent device having the thin film of the compound 1 was 33.9% measured in the air, and 47.0% measured in a nitrogen-containing atmosphere.

FIG. 8 shows the light emission spectra for fluorescent light, delayed fluorescent light, and total fluorescent light of the organic photoluminescent device having the thin film of the compound 1, and FIG. 9 shows the transient decay curve measured at 300 K thereof. The transient decay curve shows the measurement result of the light emission lifetime obtained by measuring the process where the light emission intensity is deactivated on irradiating the compound with excitation light. In ordinary one-component light emission (fluorescent light or phosphorescent light), the light emission intensity is decays monoexponentially. This means that the light emission intensity decays linearly on a graph with the semilogarithm as the ordinate. In a transient decay curve of the compound 1 shown in FIG. 9, while a linear component (fluorescent light) was observed in the initial stage of observation, a component that deviated from the linearity appeared after several microseconds. The later component is light emission of the delayed component, and the signal thereof added to the initial component appears as a long tail curve on the longer time side. Thus, the measurement of the light emission lifetime revealed that the compound 1 was a light-emitting material that contained a delayed component in addition to a fluorescent component.
